Handling Fiberoptic Components and Cables 23

Mating Optical Connectors

• Clean both connectors prior to mating. Any small particles trapped during the mating

process can permanently damage the connector.

• Insert the appropriate connector ferrule into the adapter smoothly. Do not allow the fiber

tip to contact any surface. If the tip accidentally contacts a surface before mating,

stop

Re-clean the connector and try again.

• Tighten the connector until it is finger tight, or to the torque specified by the connector

manufacturer. Do not over-tighten the connector as this can lead to optical loss and con-

nector damage.

• Check the optical insertion loss. If the loss is unacceptable, Remove the connector, re-

clean both ends of the mate, and reconnect. You may have to repeat this process sev-

eral times before a low-loss connection is made.

• After you make the connection, monitor the stability of the optical throughput for a few

minutes. Optical power trending (slowly increasing or decreasing) is caused by the slow

evaporation of alcohol trapped in the connection. Continue to monitor optical power until

it stabilizes. If the loss is unacceptable, reclean the connectors and start again.
